Detecting Bell correlations in a Bose-Einstein condensate — •Adrian Braemer and Martin Gärttner — Kirchhoff-Institut für Physik, Heidelberg

Bell correlations are the strongest type of quantum correlations and serve as a resource in many quantum information processes. They are detected through violations of Bell's inequalities, such as the CHSH inequality. This has been shown in many experiments typically using discrete-valued observables. For continuous variable systems violation has been achieved using squeezed states of light. However, highly entangled states have also been demonstrated with ultracold atoms. Motivated by this we propose a scheme to detect Bell correlations in a spinor BEC allowing a Bell test on a mesoscopic ensemble of massive particles.
